Kliegl Patch Bay

Nice Kliegl SafePatch!! You couldn't energize the circuit until the patch was complete as the breaker handle would close over the patch handle. No hot sockets and automatic disconnect on removal. Patch cables were counterweighted with weights on sheaves, but they would get tangled easily if you patched or unpatched too fast. No worries as there was a door on the end of the cabinet that you could walk in and straighten out the wiring. The patch panels were fragile and cracked easily. I would take this over a slide patch any day [as long as there was room for it].
I used to use one of those quite a bit (long ago) but it was tiny in comparison. As I recall it had 12 3.6kw dimmers and the console was a two scene with split crossfaders. The same venue had the houselights on motorized autotransformers with control boxes in the box office, lobby, booth and backstage.

Fond memories. I remember shop drawings for a patch bay going into one of the Vegas casinos that had so many circuits it had to be a two story unit in order to get every patch chord long enough to reach every dimmer. ( that was the disadvantage with safPatch. You could not place cuts close together. And it was spendy what with all the extra circuit breakers )
I had the same thought. Someone must have decided keeping the control wires short was more important than the load wiring. Most installations of this type had the dimmers under the stage in the basement and the patch panel at stage level or one floor up on a fly floor.
Interesting to note: 3K dimmers had 4 holes, 7K had 6 holes, 12K had, I don't remember, I think 6 as well?

I agree on the preferences between this patch bay and a slide patch. This patch bay facilitated easier re-patching between scenes when needed. I never liked slide patches. I dealt many while on tour around the country.

12K had 6 holes; 5-20 amp holes and one 50 amp hole, which allowed three more 20 amp circuits to be added through a 50 amp transfer cable.
Re-patching between scenes would be the primary reason I would have considered placing the patch bay in the control booth.
There were a number of architectural dimmers in this install that served other parts of the performing arts complex so the dimmer racks did end up close to the center of things, but not the center of the theatre.
David North you will be happy to know each and every one of those pig tails in the patch bay are now gone having been replaced by a Sensor dimmer, lots of Sensor dimmers.
They had been planning to replace the system and had most of the paper work done, but the funding was on hold for years. After the fire department was called when the patch bay started smoking, the funding was found.
